Winlink is a worldwide radio messaging system that uses amateur band frequencies to provide interconnection services that include email with attachments, emergency and relief communications, and message relay. The entire system is built and administered by volunteers.
Merrimack Valley Amateur Radio Association, Inc. supports a Hybrid Gateway system which utilizes HF and VHF frequencies. The system is also fully functional when the internet is not available.
